WIRE-TWISTING TOOL.

Specification of Letters Patent.

Patented Uot. 24L, 1916.

Application filed January 4t, 1916. Serial No. 70,113.

To all whom it may concern:

Be it known that I, PERL F. SWEENY, a citizen of the United States, residing at Tulsa in the county of Tulsa and State of. Oklahoma, have invented new and useful Improvements in Wire-Twisting Tools, of which the following is a specification.

The invention relates to a wire clamp, and more particularly to the class of wire twisting tools.

The primary object of the invention is the provision of a tool of this character wherein the meeting ends of wire lengths can be spliced or joined together when clamped in the tool, the tool being of novel construction to assure the tight twisting of the ends of the wire for the joining thereof.

Another object of the invention is the provision of a tool of this character wherein one of the jaws is adjustable so as to position the same relative to the other jaw for the firm clamping of ends of wires to be spliced or joined together.

A further object of the invention is the provision of a tool of this character which is simple in construction, thoroughly reliable and efficient in operation, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a side elevation of a tool constructed in accordance with the invention; Fig. 2 is a fragmentary vertical longitudinal sectional view thereof; Fig. 3 is an enlarged sectional view on the line 33 of Fig. 1; Fig. 4: is a perspective view of one of the jaws; Fig. 5 is a perspective view of the other jaw; Fig. 6 is a side elevation of the lever or handle for operating one of the jaws.

Similar reference characters indicate corresponding parts throughout the several views in the drawings. I

Referring to the drawing in detail, the tool comprises a head 5, preferably of substantially circular shape, having formed therein a T-shaped slot 6 which opens through the periphery of the head at one side thereof, while integrally formed with the latter are oppositely extending handles 7 and 8, respectively, which are disposed slightly out of alinement with each other so that the branch of the slot 6 opening through the head will extend parallel and at one side of the handle 7 for the convenient insertion of the ends of the wire in the head to be twisted by the tool. Mounted in the slots 6 in the head 5 are the opposed cooperative adjustable and movable jaws 9 and 10 respectively, which have their inner opposed working faces formed with spirally grooved channels or seats 11 for receiving the ends of the wire to be twisted when clamped thereby, the spiral channels of the grooves being designed to guide the ends of the wire during the twisting operation thereof. The adjustable jaw 9 in its outer face is formed with a T-shaped slot 12 which opens through the said outer face and is longitudinally disposed for a portion of the length thereof, and in this slot is engaged the head 13 of an adjusting screw 14 which is passed through the head 5 in a suitable opening therefor, and carries a winged nut 15 so that the screw 14 can be tightened on the adjustable jaw 9 in the head, yet on the loosening of the screw the jaw can be laterally moved so as to vary the disposition thereof relative to the movable jaw 10, the jaw 9 being of substantially wedge-shape and works against the beveled face 16 formed at one end of the cross branch of the slot 6 so that on the lateral movement of the jaw 9 it will approach or recede from the jaw 10 within the head, thereby varying the distance between the same for the clamping of wire ends thereby in a manner presently described.

The movable jaw 10 has formed in its outer face a substantially T-shaped slot 17 which extends transversely thereof, while the head 5 is bifurcated as at 18 for a distance of its periphery to receive the cam 19 of an actuating lever 20, and through this head 5 and the said cam 19 is passed a pivot 21 which eccentrically mounts the cam in the head, the said cam being formed with a curvilinear T-shaped rib 22 which engages in the T-shaped slot 17 formed in the movable jaw 10 so that on actuating the lever 20 the jaw 10 will be moved toward and away from the adjustable jaw 9 in the slot 6 for the clamping and unclamping of the ends of the wires to be twisted.

The movable jaw 10 at opposite ends is formed with flanges 23 which work against opposite side faces of the head 5 so as to prevent lateral displacement of the movable jaw 10 in the slot 6 in said head when thesaid jaw 10 is actuated by the lever 20 for the clamping or unclamping' of the ends of the wires. When the wire ends are clamped between the jaws 9 and 10 and the handles on the said head, a pair of jaws arranged inth'e slot, means-for adjusting one of the jaw relative to the other, a cam eccentrically pivoted in the head and actuatingthe other jaw to cause the same to approach and recede from the first named jaw, and a lever on the cam for actuating the same.

2. A wire twisting tool comprising a head having a slot opening through the periphery thereof, a wedge shaped jaw mounted in said slot, said slot being formed with a beveled surface to cooperate with the wedge shaped jaw, means engaged in the wedge shaped jaw and the head for permitting adjustment and the locking of the jaw, a movable jaw in said slot, a cam eccentrically pivoted in the head and connected with the movable jaw to actuate the same for bringing it toward or away from the adjustable jaw, and means for actuating the cam.

In testimony whereof I afiix my signature in presence of two witnesses.
